After starting engine, let idle for three minutes, then rev engine up to 3,000 rpm under no load to
purge air from the high-pressure chamber of timing chain tensioner (primary). Engine may pro-
duce a rattling noise. This indicates that air still remains in the chamber and is not a matter of
concern.

INSPECTION AFTER INSTALLATION

●

Check for leaks of engine coolant using radiator cap tester adapter [SST: EG17650301 (J33984-A)] and
radiator cap tester (commercial service tool). Refer to 

CO-10, "LEAK CHECK"
